The Toyota T series is a family of inline-4 automobile engines manufactured by Toyota beginning in 1970 and ending in 1985. It started as a pushrod overhead valve (OHV) design and later performance oriented twin cam (DOHC) variants were added to the lineup. Toyota had built its solid reputation on the reliability of these engines.

Australian Formula 2, sometimes abbreviated to AF2 or ANF2, is a "wings and slicks" formula racing category in Australia. The category is one of Australia's oldest, dating back to 1964. The current format of AF2 was introduced in 1978. Brian Shead of Cheetah Racing Cars and Garrie Cooper of Elfin Sports Cars were largely responsible for the development of the format, which was devised to suit the needs of Australian drivers, most of whom had little or no sponsorship and had to bear the costs of racing out of their own pockets.
